Parents need to know that this popular crime show features strong doses of graphic violence, as well as lots of blood, drug content, and sexual situations. Although the series' focus is on solving crimes and seeking justice, the violence is sometimes gratuitous, including a notable emphasis on murdered women. Character development is much less important than depicting the crimes; as a consequence, the show lacks a certain emotional resonance. Plots focusing on unusual lifestyles are treated with respect.
